Vehicle storage
If you intend to store the vehicle
for more than three months, have
the maintenance operations described
on this page performed.<
Preparations for storageHave your BMW center perform the fol-
lowing procedures:
1 Clean and apply a rustproofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in ac-
cordance with approved repair pro-
cedures. Washing the vehicle, any in-
terior cleaning and subsequent paint-
and chrome care, and cleaning any
rubber seals for the hood and doors,
should be carried out in compliance
with approved procedures as well
2 Change engine oil and oil filter at op-
erating temperature. As an additional
corrosion protection measure, an an-
ticorrosive agent can be added to the
engine when refueling in accordance
with the manufacturer's instructions
3 Check the coolant level and concen-
tration and top off if necessary
4 Fill the fuel tank completely to pre-
vent the formation of condensation
5 Increase the tire inflation pressure to
51 psi (350 kPa).
Before parking the vehicle1 Dry the parking brake and footbrakes
completely to keep the brake discs
and drums from corroding
2 Park the vehicle in a covered, dry,
and well-ventilated space. Place the
transmission in first gear or set the
selector lever to the "P" position.
Chock the wheels to prevent the ve-
hicle from rolling if necessary. Do not
apply the parking brake
3 Remove the battery, charge it com-
pletely and store it in a cool (but
frost-free) room
4 Remove the hardtop
* and store it
separately. Refer to page 121
5 Close the convertible top.
During storageRecharge the battery every six months.
If it is not recharged, it will not be ser-
viceable. Every time the battery drains,
especially over extended periods, its
service life is reduced.
Removing the vehicle from
storageRecharge the battery if the "Magic
Eye"
* turns black. Refer to page 162.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty

The lamps and bulbs are essential fac-
tors contributing to the safety of your
vehicle. For this reason, follow the in-
structions below carefully when replac-
ing a bulb. If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the electri-
cal system, switch off the electri-
cal accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage, com-
ply with any instructions provided by
the bulb manufacturer.<

Changing a wheel Battery Driving with the space-saver
spare tireDrive cautiously. Do not exceed a speed
of 45 mph (80 km/h).
You can anticipate changes in vehicle
handling such as delayed braking re-
sponse, longer braking distances and
changes in self-steering properties
when approaching stability limits.
The changes in handling characteristics
will be even more pronounced in con-
junction with winter tires.
Only one space-saver spare tire
may be mounted at one time. Re-
install wheels and tires of the same size
and specification as soon as possible.
Maintain correct tire pressures. Refer to
page 28.<
Installation locationThe battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 40). Release the two fasteners
plus an additional fastener in the upper-
center side trim panel by turning a
screwdriver or a coin 1/4-turn counter-
clockwise. In order to remove the stor-
age tray, slide the side trim panel
slightly upward.46cde045
Charge conditionYou can read the charge condition of
the battery with the "Magic Eye"
*
(= hydrometer):
>Green: adequate charge
>Black: not adequately charged. The
battery must be recharged. Please
contact your BMW center for addi-
tional information
>Yellow: replace the battery.
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for driving
short distances, be sure to check the
charge status often.<

BatteryBattery careThe battery is absolutely maintenance-
free, that is, the original acid will nor-
mally last for the service life of the
battery under temperate climatic
conditions.
For all questions regarding the
battery, please consult your BMW
center. Since the battery is absolutely
maintenance-free, the following infor-
mation is for your use only.<
SymbolsYou will find the following symbols on
your vehicle battery. For your safety,
please be cautious whenever you work
with or near the battery.
Before handling the battery,
please read the following infor-
mation.
Wear eye protection. Do not al-
low particles containing battery
acid or lead to come into con-
tact with your eyes, your skin, or your
clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Do not allow children to have
access to batteries and battery
acid.
Never allow sparks or open
flame near the battery. Do not
smoke in the vicinity of the bat-
tery. Avoid sparks from electrical cables
or electrical equipment. Turn the key to
position 0 in the steering lock when dis-
connecting or connecting the battery.
Do not short-circuit the battery termi-
nals. This creates a risk of injury from
high-energy sparks.
A highly explosive gas is
generated when the battery is
charged.
If you happen to get acid in
your eyes, rinse thoroughly for
15 minutes with clear water.
Consult a physician immediately. If you
get acid spray on your skin or clothing,
rinse with plenty of water. If acid is ac-
cidentally ingested, consult a physician
immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A drained battery can freeze. Store the
battery in areas where temperature
remains above freezing.

BatteryRemoval and installation
Do not disconnect the battery when
the engine is running. If you do so,
the ensuing voltage surge will damage
the vehicle's onboard electronics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repair and disposal must be performed
by trained technicians only.<
When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Loosen the center adjusting screw on
the battery retaining strap (use the
screwdriver included with the onboard
tool kit) and disconnect the strap.
When installing a battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery, be sure
that it is mounted properly and that
the retaining bracket is installed with the
center adjustment screw, otherwise, the
battery will not be adequately secured
in case of an accident.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running.
Before performing any work on
the electrical system, be sure to
unclamp the cable from the battery's
negative terminal. Failure to do so can
result in short-circuits, a fire or per-
sonal injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle's electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If you intend to store the vehicle for
longer than 12 weeks, remove the bat-
tery, charge it and store it in a cool and
dust-free room where there is no dan-
ger of freezing. During storage, have
the battery recharged every 3 months.
Also, recharge the battery before it is
reinstalled. If this is not done, the bat-
tery will not be serviceable. Every time
the battery is drained, especially over
extended periods, its service life is
reduced.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery to prevent it from tilting
during transport.<
Storage periods during which
the battery is disconnected are
not taken into consideration by the
Service Interval Display for changing
the brake fluid.
For this reason, be sure that the brake
fluid is changed every two years, re-
gardless of the information displayed.
Read and comply with the information
on page 136 covering this subject.<

168n
Do not use spray starter fluids to start
the engine.
If the battery is drained, the engine can
be started using two jumper cables and
another vehicle's battery. Use only
jumper cables with fully insulated
handles on the terminal clamps.
Do not touch the parts conducting
electrical current while the engine
is running. Failure to comply with this
creates a risk of fatal injury.<
Carefully comply with the following in-
structions to avoid personal injury or
damage to one or both vehicles:
1 Be sure that the battery on the sup-
port vehicle is also rated at 12 volts,
and that the capacities of the two
batteries (Ah) are roughly comparable
(printed on casing)
2 Leave the drained battery connected
to the vehicle's electrical system
3 Make sure that there is no contact
between the bodywork of the two
vehicles – short circuit risk!
4 Start by connecting the jumper cable
from the positive terminal of the sup-
port vehicle to the positive terminal
connector located in your BMW's
engine compartment. The cover of
the auxiliary terminal for jump-start-
ing is identified by a "+" sign. Refer to
the illustration. Remove by pulling the
tab (arrow 1)
5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal (–),
or to a suitable ground on its engine
or bodywork. Then connect the other
end of the cable to a ground on the
engine or on the bodywork of the ve-
hicle that is to be started. There is a
special nut provided for this on the
BMW (arrow 2)
Follow the same sequence for
connecting the jumper cables
when helping other vehicles. If you do
not, there is the risk of injury if sparks
are generated at the battery.<462de253
6 Start the support vehicle's engine
and let it run
7 Start the engine on the vehicle need-
ing the jump-start, and allow it to run
as usual. If the first start attempt is
not successful, wait a few minutes
before another attempt in order to
allow the drained battery to recharge
8 Before disconnecting the jumper
cables from your BMW, turn on the
rear window defroster and set the
blower to the highest speed; allow the
engine to run approx. 10 seconds.
This will prevent a voltage surge from
the voltage regulator to the electrical
accessories
9 Then disconnect the jumper cables in
reverse sequence.
Depending on the reason for the mal-
function, recharge the battery.
